Abstract

Det er beskrevet injiserbare depotpreparater som omfatter en polymermatriks som har et flertall av bionedbiytbare, biokompatible polymerer hvor hver polymer av flertallet av polymerer har en spesifisert vektmidlere molekylvekt; og polymermafriksen har en bred molekylvektsfordeling av flertallet av polymerer; et oppløsningsmiddel som har en blandbarhet i vann på mindre enn eller lik 7 vekt-% ved 25°e, i en mengde effektiv for å mykne polymeren ved å danne en gel med denne og et fordelaktig middel. Preparatene har vesentlig forbedret skjærfortynningsoppførsel og redusert injeksjonskraft, hvilket gjør preparatene lett implanterbare under en pasients kroppsoverflate ved injeksjon.Injectable depot compositions are disclosed which comprise a polymer matrix having a plurality of biodegradable biocompatible polymers wherein each polymer of the plurality of polymers has a specified weight average molecular weight; and the polymer matrix has a broad molecular weight distribution of the majority of polymers; a solvent having a miscibility in water of less than or equal to 7% by weight at 25 DEG C., in an amount effective to soften the polymer by forming a gel therewith and an advantageous agent. The compositions have significantly improved shear thinning behavior and reduced injection power, making the compositions easily implantable under a patient's body surface at injection.
